Wage and Productivity Dispersion in United States Manufacturing: The Role of Computer Investment
利用工厂层面数据，研究发现工厂间工资和生产率离散度近几十年大幅上升，且计算机投资分布的变动是重要原因。
Using establishment-level data, we shed light on the sources of the changes in the structure of production, wages, and employment that have occurred over recent decades. Our findings are: (1) the between-plant component of wage dispersion is an important and growing part of total wage dispersion; (2) much of the between-plant increase in wage dispersion is within industries; (3) the between-plant measures of wage and productivity dispersion have increased substantially over recent decades; and (4) a significant fraction of the rising dispersion in wages and productivity is accounted for by changes in the distribution of computer investment across plants.
